The work is on the picture attached, but a = 1
Hope this helps!!
Y=mx+b or -2=-1 x 2+b, b= -2(-1)(2) b=0
Therefore the equation of the line is
y=-1x
6 / 1/3 = 18
Hope I helped!

The correct answer would be 3
Answer:

After 7.40 years it will be worth less than 21500
Step-by-step explanation:
This problem is solved using a compound interest function.
This function has the following formula:

Where:
P is the initial price = $ 34,000
n is the depreciation rate = 0.06
t is the elapsed time
The equation that models this situation is:

Now we want to know after how many years the car is worth less than $ 21500.
Then we do y = $ 21,500. and we clear t.

After 7.40 years it will be worth less than 21500
